Patented Sept. 3, 1935 UNlTED S'ila'ln ultime fiingiiti'l OFFICE i' 7 Claims.

This invention relates to a device or apparatus for holding, cutting and breaking glass. It is necessary to cut panes or pieces of glass to t various applications thereof and this work is commonly done in stores selling glass, lumber yards and other similar establishments. It is desirable to have a device by mean of which the glass can be conveniently and easily handled and positioned for cutting and one in which it can be accurately and quickly broken along the cut after the same is made.

It is an object of this invention to provide a very simple and eicient device having supporting means for a piece of glass, a member having a surface against which the glass can be pressed, a member including a yielding means engaging the glass to hold it against said surface, a straight edge along which a tool can be moved for making a cut in said glass and means for resiliently urging said member toward said surface. i

It is a further object of the invention to provide a device having means for supporting a pane of glass, a member having a surface engaged by said glass, a straight edge along which a tool can be moved for making a cut in said glass and movable means for engaging said glass to break the same along said cut.

It is another object of the invention to provide a, member having a surface for supporting a piece of glass, a second member extending at right angles thereto having a surface to be engaged by said glass, a member swingable toward and from said surface, a yielding means on said last mentioned member for engaging the glass, a resilient means urging said last mentioned member toward said surface and a handle for swinging said last mentioned member away from said surface.

It is still another object of the invention to provide a device for holding and cutting glass comprising a member having a surface against which the glass is pressed, another surface extending at an angle to said surface making a corner on said member, a straight edge adjacent said corner along which a tool can be moved for making a cut in said glass and movable means for pressing the glass toward said corner to break the same along said cut.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawing, in which like reference characters refer to similar parts throughout the several views and in which:-v

(Cl. 49u48) Fig. 1 is a view in front elevation of the device;

Fig. '2 is a top plan View;

Fig. 3 is a horizontal section taken on line 3-3 of Fig. 1 as indicated by the arrow;

Fig, l is a vertical section taken on line ll-d of Fig. 3 as indicated by the arrow;

Fig. 6 is a view similar tol Fig. 3, some parts being omitted illustrating the manner of breaking the glass, Figs. 2 to 6 being shown on an enlarged scale.

Referring to the drawing, a glass manipulating device is shown comprising a member lll. While this member might be made of various materials, in the embodiment of the invention illustrated, it is shown as made of wood. Member l@ is illustrated as of general rectangular form in cross section, the same having its front part cut away to have a surface Nia thereon which, in the position of the device illustrated, extends horizontally. A member ll, shown as rectangular in cross section, is secured on the top of member lil and has a scale ila thereon. The out away portion of member il! also forms a vertical surface lill) at right angles to surface lila and a member l2 is provided also of rectangular form in cross section, the same having one flat surface ush with surface lub, said member l2 extending at right angles to member lli. As illustrated member l2 is mortised into member lll at its lower portion and connected thereto by a pair of headed and nutted bolts i3. As illustrated in Fig. 3, the portion of member lil below surface ita is beveled off in front of member l2. Member l2 has a member ll set into the edge thereof also rectangular in cross section and having a scale lila on its front surface. Member ll) has secured to the bottom thereof by a plurality of screws l5 a plate l5. Plate l5 is bored to receive the reduced end of a pintle ll rotatable in said plate, said pintle il' being secured to a member i3 extending upwardly from plate i6, the same being illustrated as in the form of an angle bar. Member ll will be secured to member i8 in any suitable manner as by welding. Member i8 also has secured to its upper end a pintle member l il having a portion extending through a bracket Ztl formed of an angle ironk and secured to vertical member l2 adjacent the upper end thereof by bolts 26a. Pintle member i9 above bracket fil has a rod 2l secured thereto extending forwardly and laterally adjacent the outer end of which is secured one end of a tensile coiled spring 22 secured at its other end by a headed and nutted bolt 23 in bracket 2i?. Member I3 has secured. to its side adjacent member i2 a strip or pad 2d of yielding material. While member 24 may be made of rubber or some rubber compound, in practice a strip of fabric belting has been found to be very suitable. The pintle El extends below the plate i5 and projects laterally, the same having secured thereto a handle member 25. it will be seen that spring 22 urges member I8 in a clockwise direction toward. member and said member may be swung in the opposite direction by handle 25. A stop pin loa upstands from member E6 limiting swinging movement of member lcl. As shown in Fig. 8 plate i6 extends at an angle to the front edge of member iQ. A small slide 25 is mounted on one side of member i3, the same having an elongated slot Ta therein through which pass spaced screws El secured in member i3. Slide 2G is freely movable upwardly and downwardly as permitted by slot and screws 2l. Said slide has a portion cut away at its lower end and said end is bent laterally as shown in Fig. l. The lower end of member 25 at its full width is arranged to engage the outer end of plate i G when said member is in its lowest position.

A member 28 is provided illustrated as in the form of a T-bar, said member extending vertically parallel to member l2. Member 25 has its stem portion and a part of its flange cut away at the top and bottom, the remaining part of the flange being bent substantially at a right angle. At the lower end this bent portion 28a is apertured to have the pintle il pass therethrough and the bent portion 28h at the upper end is apertured to have the pintle i9 pass therethrough, this portion 28h resting on and being supported on bracket f It will be understood that pint-le members il and B9 are co-axial. Member is thus mounted for swinging movement about the axis of said pintles. Bracket 2S has a notch 20a cut therein to accommodate the movement of member 28 when the latter is swung to its extreme position. Member 2S is provided with a handle 29 intermediate its ends.

As stated, member l2 is mortised into member le and secured thereto by the bolts l 3. An angle bracket is also bolted to the top of member lil by the bolts 3l and is also bolted by the bolts 32 to member l2. A plate J3 has a horizontal lower portion overlying the horizontal flange of angle bracket 3Q through which two of the bolts 3l also pass. This plate extends upwardly at an angle to the rear side of member l2 and then extends upwardly some distance in contact with the rear side of member E2, being bolted thereto by the bolts Btl. Members l and l2 are thus held accurately and rigidly in connected position.

In operation, when it is desired to cut a piece of glass, the device is usually placed with member l2 extending vertically and member IB is swung outwardly in a counter clockwise direction so that slide 2G drops down to have the lower end of its side portion engage the edge of plate i6. Plate ES and the pad 2t are then held sufliciently away from the front surface of member l2 so that a piece of glass can readily be passed therebetween. The piece of glass is placed in vertical position with its lower edge resting on the surface ita and one fiat side thereof engaging surfaces lb and the front surface of member l2. The glass is now moved along on surface lila until it is in the desired position to be cut. The size of the glass both horizontally and vertically can readily be determined by the scales lla and lila. When the glass is properly positioned, the operator takes hold of handle 25, moving the same outwardly slightly and with one finger raises slide 26 and then allows the handle 25 and member i8 to swing inwardly or clockwise so that pad 24 is brought into engagement with the glass 35 as shown in Fig. 6. Stop pin 16a is provided to prevent excessive stretching of spring 22. The operator now takes a glass cutting tool of the type which is well known and moves the same along the outer or right hand edge of member i8, using straight edge of said member as a guide and makes a scratch or cut in the pane of glass which will be substantially opposite the outer corner of member l2 or in line with the outer surface thereof. The operator now takes hold of the handle 2g and swings member 28 in a counter-clockwise direction so that one edge thereof is swung against the glass 3G beyond member l2. The glass now breaks cleanly and accurately along the entire length of the cut. It will be seen that the glass held firmly by the pad 2&1 throughout the length thereof under the pressure of spring 22 and the same will be engaged evenly throughout the Ith thereof by member 28. A clean and accurate cut and break of the glass is thus obtained. It will be noted that it is not necessary to move the glass after the same has been cut by the tool and before the same is broken. The cutting tool can be disposed between members IB and 28 or member can be swung clockwise in front of member l 8 and the tool thus used at the right of member as shown in Figs. l, 3 and 6. After the glass is broken the handle 25 can be again swung outwardly slightly to relieve the pressure of pad against the glass, the member 26 drops downwardly engaging the edge of plate it and holding member i8 in an outward position so that the glass can be readily removed. The whole operation is thus easily and quickly performed and a perfect job can be done.

The two bolts 3l passing through the plate bracket 33 can be removed as can also the bolts 3 and member l2 can then be removed from member lo so that said members may be placed in parallel position for shipping.

From the above description it is seen that applicant has provided a very simple and efficient device for holding, measuring, cutting nd breaking glass. The structure is quite rugged, comprises comparatively few parts and requires no attention for maintenance. The device has been actually used in actual practice and found to be very successful and efficient.
